WebMay 23, 2024 · The atom of sodium has 11 electrons, 11 protons along with 12 neutrons, but Na+ contains one less electron, 11 protons along with 12 neutrons, as the ion has lost 1 electron. What are the maximum number of electrons in each shell? WebJan 29, 2016 · There are 11 electrons in an isolated atom of sodium. Explanation: From the periodic table we know that Z, the atomic number, = 11 for sodium. The sodium nucleus thus contains 11 positively charged particles. To balance this charge (this is a NEUTRAL metal atom!) there must be 11 electrons, 11 negatively charged particles circling the nucleus.
